Various stages of aluminum extrusion process

 　　1. The mold is cast with the required cross-sectional shape. 　　2. Heat the aluminum billet in the furnace until it reaches 750-925 º F. At this point, aluminum becomes a soft solid. 　　3. Lubrication, known as smut, is applied to steel billets and plungers. Black ear disease is essential as it ensures that the billet and plunger do not stick together. 　　4. The plunger applies pressure to the blank and pushes it through the mold. During this process, liquid nitrogen is used to cool the mold. Cooling can prevent the formation of unwanted oxides and extend the length of the mold. 　　5. Extruded aluminum comes out of the mold and has the same shape as the mold opening. The extrusion is pulled onto the cooling table, where it is exposed to air, water, or a mixture of both (depending on the final mechanical requirements of the metal). 　　Next is the stretcher. This can correct any twisting that may occur and straighten the metal. Improved hardness and strength during the s...

What is the use of oxygen free copper?

 　　The higher the purity of any copper product , the better its corrosion resistance, the higher its conductivity, and the less heat generated during conductivity. As the purest copper product, C101 oxygen free copper provides the best results for all copper products. 　　By removing almost all impurities, the metal structure of copper is almost uninterrupted, and by removing almost all oxygen, the oxidation of metal copper is significantly reduced, which further hinders performance. 　　Due to the high price of high-purity products, almost all uses of C101 oxygen free copper are highly specialized. This includes: 　　Excellent audio/video applications - Quality critical high-end audio/video applications will use copper wire made of C101 oxygen free copper. 　　The increase in conductivity of C101 oxygen free copper for large industrial transformers can reduce the diameter of the internal wiring in the transformer, thereby reducing the amount of copper used and the overall in...

Stainless steel magnetic standard

图片
 　　The stainless steel grade plays a role in influencing factors, but generally speaking, stainless steel alloys have magnetism, and they must meet the following requirements: 　　The alloy must contain iron (Fe). 　　The crystal structure of stainless steel alloy must be arranged in martensite or ferrite structure. 　　Firstly, as stainless steel is a type of steel, its chemical composition must contain iron. This makes stainless steel magnetic. 　　The second requirement is that the crystal structure of stainless steel must be arranged into ferrite or martensite structure. If stainless steel is mainly composed of austenitic structure, it will not have magnetism. 　　As we have already mentioned, corrosion resistance is not related to magnetism. In stainless steel, corrosion resistance depends on the concentration of chromium (sometimes molybdenum). The more each, the better the corrosion resistance.
